T0 on whom it may concern.-

Be it known that I, PAULIN COUPETTE, chief engineer, a subject of theKing of Prussia, German Emperor, residing at 11 Kaiser Wilhelm Ring, inthe city of Cologne, King dom of Prussia, German Empire, have invented acertain new and useful Advertising Device, of which the following is aspecification.

This invention relates to advertising devices; and it consists,substantially, in the details of construction and combinations of partshereinafter particularly described, and pointed out in the claims.

Though applicable to different purposes, the invention has referencemore especially to devices employed in cars and similar vehicles forsuccessively indicating the several stations lying along the routetraversed by the car; and one of the principal objects of the inventionis to provide a device of this character which is both simple inconstruction and effective in use.

A further object is to provide a device of the character referred towhich comprises but few elements and which is reliable in operation,besides possessing the capacity for long and repeated service.

The above and additional objects are ob tained by means substantiallysuch as are illustrated in the accompanying drawings, in which Figure 1is a front elevation of an advertising device embodying my improvements.Fig. 2 is a transverse sectional View thereof. Fig. 3 is a similar viewof a modified form with parts broken out and also indicating the stopdevices for the intermittently-operated drum. Fig. 4 is a longitudinalsectional view broken off at one side and indicating more clearly theconstruction and organization of certain of the operative elementsemployed.

Before proceeding with a more detailed description it may be stated thatin the form of my improvements herein shown I employ a suitable casing,in the upper part of which is mounted a roller of special construction,suspended from which at intervals are a plurality of advertising-sheets,which are caused to be successively wound upon the roller and 'which arealso successively dropped to vertical position, as and for the purposehereinafter more particularly explained. I employ special means forefiecting the intermittent movements of the roller, as well as specialstop devices therefor, and while I have herein represented myimprovements in a certain preferred embodiment it will be understood, ofcourse, that I am not limited theretoin precise detail, since immaterialchanges therein may be resorted to coming within the scope of theappended claims.

Reference being had to the several parts by the designating charactersmarked thereon, a represents a casing of suitable dimensions having itsside walls connected. by crossbars w and having in the front wallthereof an upper opening I) and a lower and larger opening 0, each ofsaid openings being preferably closed by glass to enable the matter onthe advertising-sheets to be readily observed or read from without.Mounted between the side walls of the casing at a suitable height is theshaft y of a rotatable drum, constructed of duplicate disks d, disposeda suitable distance apart upon the shaft, said disks being formed atintervals with sockets d receiving the reduced end portions d of aseries of rods 6, preferably constructed of spring material. Each of thesaid rods 6 has secured thereto in any suitable manner an edge of asheet f, on each side of which suitable advertising matter may be placedor printed. If desired, one face of each of said sheets may have printedthereon at the proper place the name of astreet or car-station, becomingvisible through the opening I) in the casing, while the space of theopposite side of the sheet may be taken up by advertising matter of anyother preferred character.

As shown in Fig. 2, the shaft of the drum has mounted thereon a ratchetwheel 9, which is engaged by a spring-pawl 9 carried by a lever Z,pivoted at one of its ends to the side Wall 1 of the casing a, asindicated at 1 while the other or free end thereof has applied thereto arod 1 provided with a head Z working in a small cylinder 0, as and forthe purpose hereinafter more particularly explained. Pivoted to the saidlever Z is the upper end of a rod 'L, the lower end of which terminatesin branches a, each provided with a shoe t the said rod & being formedwith a slot i near its lower end and having projecting therefrom at aproper height a pin i A guide-pin 1' passes through the said slot and issecured in the said wall 1 of the casing a, while exerting a downwardpressure on the pin 4& is the free end or extremity of a spring k,having its other end or extremity secured ments of the said rod 11.

to the wall 1 of the casing, as clearlyindicated in Figs. 2, 3, and 4.Working on a short shaft a mounted in the sidewall 1 of the casing a, isa two-armed lever 11,, to which an oscillating movement may be impartedby rocking the said short shaft 11. by means of a lever a connectedthereto, the free end of the lever being moved by hand or automaticallyin any suitable manner. On imparting a rocking movement to the shortshaft a the said arms of the said lever u will be caused to alternatelyengage the shoes i of the branches t" of the said rod i, and thus willthe rod be reciprocatedvertically. On each upward movement of the rodthe ratchet-wheel y will be caused to move a predetermined distance bymeans of the spring pawl 9 and the drum and shaft will be movedaccordingly, retrograde movement of the drum being prevented by a pawl 9which successively engages the teeth of the ratchet-wheel g. As the drumis intermittently operated the advertising-sheets f will be successivelycarried over and around therewith, as indicated in Figs. 2 and 3, tobring to view the advertising matter contained thereon, as will bereadily understood. Each upward movement of the rod i is against thepressure of the free end or extremity of the spring k, bearing upon thepin i and consequently said spring operates to again carry the roddownwardly, it being understood that the lever Z partakes of both theupward and downward move- On each upward movement of the lever l the rodZ? is elevated therewith, and the said rod Z is also carried downwardlytherewith, and in the said up and down movements of the rod 1 asteadying or regulating effect on the lever Z is had, due to the workingof the head Z in the cylinder 4;, as will be apparent.

In order to retain the sheets f in proper relation about the drum andalso to regulate the proper dropping of the sheets to vertical position,I preferably employ suitable pressure devices bearing upon thesheetssuch, for instance, as indicated at h h, Figs. 2 and 3the saiddevices consisting of a plurality of springs properly disposed withinthe up per part of the casing a, the free ends thereof being bent orbeveled and arranged one behind the other and bearing upon thesuperposed sheets and yielding sufficiently to suecessively release thesheets as the drum is intermittently operated.

As shown in Fig. 3, I substitute for the spring-pawl g of Fig. 2 aspring-pressed pawl m, carried by the lever Z and I also employ anotherspring-pressed pawl n, successively engaging the teeth of theratchet-wheel 9, so as to prevent retrograde movement of the drum. Asalso shown in Fig. 3, I preferably employ stop devices for preventingthe drum from being carried around too far at each intermittent movementthereof, said devices comprising another gear-wheel 0, mounted upon theshaft of the drum alongside the gear-wheel g, the teeth of saidgear-wheels being disposed in opposite directions, as indicated.

Mounted upon a stud r, secured to the wall 1 of the casing a, is an arm8 of a pawl'g, said pawl being normally pressed out of engagement withthe teeth of the ratchet-wheel 0 by means of a s ring p. Carried by thelever Z near the fiee end thereof, is a spring t, which as the lever Zis carried upwardly through the motion communicated thereto by the rod 6effects a yielding engagement with the said arm 8 of the pawl (1,thereby causing the latter to swing upon the stud r and engage with oneof the teeth of the ratchet-wheel 0 immediately succeeding each movementimparted to the drum by the actuating-pawl for the ratchet-wheel g.

I may sometimes employ an electric battery w, from which suitable wireconnections may lead to an alarm device, as bell w which is sounded eachtime a movement of the intermittently-operated drum takes place. Asshown in the drawings, a contact-spring z and the motion-transmittinglever I, carrying an electric contacting piece 2, are included in theelectric circuit.

The rods e of the drum being formed of spring material are easily sprungto an extent suflicient to enable the reduced ends thereof to beinserted within the sockets in the disks, and the advertising-sheets areapplied to the rods by simply loo ing one edge thereof, as shown, andthen sipping the rods through the loops. This is an advantageous featureof construction, since the sheets may thus be applied and removed veryreadily, as is apparent. In order to hold the sheets taut when in asuspended or vertical position, each sheet may be provided with a rod atthe edge thereof opposite to the edge at which it is applied to thesupporting-rod, and by reducing the ends of rods 6 it will be seen thatannular shoulders are formed, which prevent the rods from endwisedisplacement between the disks.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. An advertising device, comprising a drum constructed of duplicaterigid disks having corresponding sockets therein, rods of springmaterial having the ends thereof reduced and seated in the said sockets,advertising-sheets each having an edge thereof looped and slipped overone of the springrods, and means for imparting an intermittent rotarymotion to the drum.
